Clear 2.2.3 (fixes & polish, now out!)

@phillryu

• Fixed ‘cash register sound’ bug

Uh-huh, a wild $ hasn’t appeared yet.

@phillryu

• Fixed a couple heatmapping cosmetic glitches

Any ETA on the below?

@phillryu

I will add this to the polish list for graphic themes. I feel like we are calculating it for heatmap themes based on color values but it might be simpler for graphic themes to hand assign one.
